Hi,

I'm sorry, that was my fault.

The sourcecode for that program is in
"crosscompile-windows/maxima_longnames.c". The program can be compiled
using a C compiler and be copied to the Maxima-binary directory. It is
build when the installer is build using the crosscompiling procedure on
Linux (which is CMake-based), but it is not included in the usual
automake build.

The reason for that program was (quoting my Git commit message):

    Fix the plotting problem with Clisp/Windows and long user names.

    Clisp has problems with generated Windows 'short names' e.g.
    echo %TMP%
    C:\Users\TESTTE~1\AppData\Local\Temp
    Windows generates a short name for the temporary dir, when the
    username contains spaces and is longer than 8 chars.
    Correct that path name to the 'long version', so that Clisp has
    no problems with long user names and plotting commands.

It is also documented in 'maxima.bat':

rem change 'short names' (e.g. "C:/Users/TESTTE~1/AppData/Local/Temp" to
rem long names (e.g. "C:/Users/test test/AppData/Local/Temp" -
rem CLISP has a problem with these short names.

Don't know, if other Lisp's are affected too. I implemented that for CLISP.

Sorry for that, will fix it soon (I will be abroad for a few days, don't
know, if I have time and a good internet connection then...)

I have not seen these errors. How did you build Maxima? Using a
Lisp-only build? Mingw? Cygwin?
